Natural wonders: “Under the Sea 3D” is loaded with remarkable underwater footage
It’s a scene of startling beauty: Countless garden eels, some more than 6 feet long, rise out of their ocean-floor burrows and, as they waver in the ocean current, they resemble a field of tall grasses in a gentle breeze.
This shot, from the new IMAX documentary “Under the Sea 3D,” now showing at Celebration North, was costly, time-consuming and required mountains of patience.

At the ocean’s deepest point, the water pressure is the equivalent of having about 50 jumbo jets piled on top of you. Yet even here life thrives, according to scientists who have pulled a plug of dirt from the seafloor.
The sample was taken from the Challenger Deep, which is nearly 7 miles (11 kilometers) deep. The soil was packed with a unique community of mostly soft-walled, singled-celled organisms that are thought to resemble some of the world’s earliest life forms.
They’re called foraminifera, single-celled protists that construct shells. Protists are a kingdom of celled organisms distinct from animals, plants, and fungi. Other types of protists include algae and slime molds.
There are an estimated 4,000 species of living foraminifera. They inhabit a wide range of marine environments, mostly on the ocean bottom, though some live in the upper 300 feet (100 meters) or so of the ocean. A few species are found in fresh water and on land.
However, the discovery of 432 foraminifera living in dirt from the Challenger Deep surprised Hiroshi Kitazato, a program director at the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) in Yokosuka.
“We are surprised that so many [bottom dwelling] foraminiferaâ€”in particular so [many] soft-shelled formsâ€”live in the Challenger Deep, because former reports gave us the impression the world’s deepest point is scarce in any [celled organisms],” he said.Read More
